south, I hope you're right because that all sounds pretty good. If things do go down like that, then there might not be much to lament.
However, what about the things discussed in the article? Will the next M5 use the N64-derived motor that is in the "X6 M", as this article claims? If it does, I think there's not really a whole lot of difference than if they were to use the N54 in an M3. Do you disagree? Now of course, it doesn't mean that they will use the N54 as the basis for an M3 engine. That would be jumping to conclusions a little too prematurely. I am just saying that once the M5 goes that route (if it did) it can no longer be argued that BMW will develop unique turbo engines for all their M passenger cars. Maybe people here won't care much about what the M5 is powered by though? Arguably this whole thread is off topic for this board anyway. Maybe. But it would still be tough not to worry how things might come out a few years later if this same philosophy is applied to the M3.
